Overview¶

This project demonstrates the use of the OpenBCI Ganglion, as well as a MyoWare muscle sensor, to control a small robotic car. Previous work using the myoware sensor can be seen here. The OpenBCI Ganglion is a board that will allows for the detection of brain activity. For this project, we will be detecting Alpha Waves and using them as a control input to the car. Much of this work is a derivative of previous efforts by EEG Hacker and OpenBCI.

Getting Started¶

This project will be using a slightly modified version of the OpenBCI GUI found here. This code is written and run with processing.

The hardware used in this project is:

• 2 x MBED LPC1768
• 1 x OpenBCI Ganglion
• 1 x Gold cup electrodes
• 1 x Conductive Paste
• 1 x Muscle Sensor with extension boards
• 2 x nRF24L01 RF transceiver
• 1 x H-Bridge breakout
• 1 x Battery Holder with Barrel Jack
• 1 x breadboard compatible barrel jack
• 2 x DC Motors
• 1 x Shadow Chassis

The Robot¶

The instructions for building the Shadow Chassis can be found here. Note that we did not use most of the parts listed in the guide.

Communication¶

Ganglion¶

The ganglion we are using was loaded with an older version of firmware, which needed to be updated in order to program it. Although we did not end up changing any code on the device, the instructions to update the firmware and to program the Simblee can be found here.

Processing¶

This project is currently only compatible with Processing 2.2.1 which can be downloaded from here.
